Аннотация: To study spontaneous combustion and explosion of brown-coal dust, an experimental setup was designed and a method for analysis of these processes was proposed. Kinetic parameters (activation energy and preexponent) of the brown coal from the Irsha-Borodino deposit were determined. It was shown in experiments that, for certain coal/oxidizer ratios, the explosion has a two-stage character. The repeated explosion of dust is caused by thermal activation of coal at the first stage of the explosion. Mathematical models for a qualitative description of spontaneous combustion of brown-coal dust are considered.
